Abstract: PURPOSE: A recording/playing back method of an RLL(Run Length Limited) of an optical disk is provided to record a high capacity of data through length reduction of a channel bit of an optical disk by using an auxiliary modulation code for meeting the condition of d=3 and k=11 wherein d is the minimum run and k is the maximum run. CONSTITUTION: An encoder(1) consists of plural registers(10,12,14,16,18,20) outputting input 2-bit codes as the previous code(P0P1), the current code(C0C1) and the next code(N0N1) via delayers(22,24); and plural logic gates(26) logically combining the codes of previous code registers(18,20), current code registers(14,16) and next code registers(10,12) to set at least 1 of 5-bit code word(O0O1O2O3O4) output through an output buffer(28) lower than 1. The output buffer is enabled by a clock obtained from a half-divided clock signal. The encoder uses an auxiliary modulation code for meeting the condition of d=3 and k=11 if error input is generated. Therefore, high reliability of data recording is performed.
